Iron Ore Smelting Process

At the surface iron ore processing plants the iron ore is put through crushers and ball mills to break it into a uniform and more workable size and then washed with the residue going to tailings The ore is the transported to the various smelters located locally or on the other side of the world with large bulk carriers being used to ship the ore by sea

Iron ore pelletizing systems

Iron ore can be upgraded to a higher iron ore content through beneficiation This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process Also during the processing of high grade iron ores which don't need beneficiated fines which are generated can be pelletized and used instead of being

The chemistry of steelmaking The big picture

In this section we'll summarise the chemistry that is important in changing iron ore into steel Reactivity of metals Iron is a moderately reactive metal which joins readily with non-metals such as oxygen This is why we do not find pure iron in the Earth's crust Instead it is found as an ore in which iron is chemically combined with oxygen or other non-metals Most workable iron ores are rich in iron (III) oxide Fe 2 O
